motionBlurImage

Simulates motion blur. We convolve the image with a Gaussian
operator of the given radius and standard deviation (sigma).
For reasonable results, radius should be larger than sigma.
Use a radius of 0 and MotionBlurImage() selects a suitable
radius for you. Angle gives the angle of the blurring motion.

Parameters

radius

float

The radius of the Gaussian, in pixels, not counting the center pixel.

sigma

float

The standard deviation of the Gaussian, in pixels.

angle

float

Apply the effect along this angle.

channel

int

Provide any channel constant that is valid for your channel mode. To
apply to more than one channel, combine channeltype constants using
bitwise operators. Refer to this
list of channel constants.
The channel argument affects only if Imagick is compiled against ImageMagick version
6.4.4 or greater.
